When comparing a lot of different sliding miter saws, you will find that the vast majority of them either have a 10-inch or 12-inch blade, which is standard, but let’s break down the advantages and disadvantages to each.
The 10-inch blade
For example, the compact Festool Kapex KS 120 10-inch Sliding Compound Miter Saw delivers a professional and incredibly precise results whether in the workshop or on the job site.
With advanced electronics that include dual laser guides, micro-bevel adjustments, quick-release fences, and easy-to-reference scales, plus a host of other smart features to provide the best, most precise cut. There are dual lasers that accurately and clearly define what will be removed during the cut, and the three-axis adjustment controls make it easy to fine-tune the lasers, which are electrically powered, requiring no batteries.
the center-positioned handle allows ambidextrous cutting, and a two-stage trigger helps prevent accidental triggering. The rotating knob uses a rack and pinion technology to move the counter-spring balanced head. This means that once you set a bevel angle it will stay in place before you engage the dependable bevel lock.
The 12-inch blade
A example of a good 12-inch sliding miter saw is the Bosch GCM12SD 120-Volt 12″ Dual-Bevel Glide Miter Saw.
This 12-inch dual-bevel glide miter saw features a powerful 15-amp motor that delivers a smooth, accurate cutting performance with a space-saving design, exclusive to the Bosch Axial-Glide System. The square lock fences are pre-aligned to maintain a lifelong accurate cutting. This tool sports a soft-grip handle along with a combination dust chute and vacuum adaptor for best user comfort and a clean operation.
The no-loads speed of this durable saw delivers quick cuts in many different materials, and this tool is compatible with a variety of 12-inch blades with a clear lower guard to provide clear, cut-line visibility. Versatile. With bigger saws, it may also be worth investing in a good miter saw stand.
